An added benefit of solar PV is that the modules last for 25 years and require almost no maintenance.

Technology cost efficiencies

Most of the world’s solar modules are made from crystalline silicon (or sand in its basic form). As greater quantities of solar modules are produced worldwide at greater efficiencies, the cost of solar PV keeps becoming more and more competitive.

Cost savings

By offsetting the electricity purchased from your local utility, solar PV can create substantial monthly cost savings. In South Africa the general payback period of a solar PV system is 5-6 years. With a system that lasts for 25 years, this means approximately 20 years of free, clean energy!
